Abstract: 1412500 Film transport mechanism AGFA-GEVAERT AG 30 Nov 1973 [30 Nov 1972] 55702/73 Heading G2A The camera mechanism of Specification 1408645 has a further device for preventing double exposure. A toothed wheel 117, frictionally engaged with a gear (116), Fig. 3 (not shown) driven by a sun gear (119) which also drives a film spool, is locked by a spring-loaded member 211 during the film transport movement. During this movement the end 209a of a spring-loaded feeler 209 rests on the surface of the moving film 202. When end 209a enters into a film-metering perforation 202a Fig. 2 (not shown) a spring-loaded lever 216 is able to pivot anti-clockwise, so engaging member 211. This pivots clockwise, so disengaging from wheel 117. During the transport movement member 211 is engaged under the shutter release 225, so preventing it from being actuated. When member 211 is disengaged from wheel 117 it also moves away from under release 225. This still cannot be actuated, however, until the transport slider 125, which drives a transport wheel 110 which in turn drives the sun gear (119), has returned to its original position. This rotates the wheel 110 from the position of Fig. 2 (not shown) to the position of Fig. 1, so that an excision 110a therein is brought into register with the release 225, so allowing it to be actuated.

In a dial device for a radio receiver having a dial plate 10 illuminated by a pilot lamp 11, a band-like indication member 9 is accommodated in a case 8 in the form of a spring-urged coil and is driven into or out of the case by a rope 4 on rotation of a knob 2 so that the amount of indication is represented as the amount of the indication member 9 which is seen through a display window 1<SP>1</SP>. The band indicator 9 is biased by its own spring pressure either out of the case 8 towards "0" or into the case towards "10". The plate 10 is coloured so as to enable the band 9 to be easily seen. A dial (13<SP>1</SP>) Figs. 4 and 5, (not shown) marked in frequency, may be positioned in front of the band 9 and is illuminated by a lamp (16, 16<SP>1</SP>) at each end of the dial. The dial (13) is transparent and has coloured indication characters (14, 14<SP>1</SP>) and a light reflector (15) behind the band 9 coloured the same as the characters (14, 14<SP>1</SP>). The characters (14, 14<SP>1</SP>) only show up when the lamps are lit so this indicates that the dial device is in use. The dial plate 13 may be divided into upper and lower strips (13a, 13b, Figs. 6 to 8, not shown) and each strip is of complementary colour. The strips may be lit so that one is red, illuminated by a red lamp (16), and the other is blue illuminated by a blue lamp (16<SP>1</SP>). Alternatively a colour filter (19) having two different coloured sections, may be slide between a single lamp 16 and the strips (13a, 13b).

The bearing race 1 is held magnetically or otherwise on the rotating table 2 and its raceway 4 is engaged by the member 3 which may be cylindrical, partconical or spherical. The member is carried by the arm 7 which is secured to a link 9 supported by parallel springs 8 from a plate 15. The probe 6 engages the end face of the race and is carried by an arm 11 secured by a link 14 to a pair of parallel springs 12 also on the plate 15. The probe 10 is pneumatic, mechanical or inductive and is mounted in one of the links and cooperates with a baffle in the form of an adjustable screw 13 in the other link. An adjusting device 21 is associated with each of the spring arrangements to vary the measuring force and axial movement of each of the arms 7, 11 is limited by screws 26 co-operating with grooves in the links. The arm 7 is supported by a spring joint 28 so that the member 3 can be withdrawn from the raceway 4 upon operation of a cylinder 28. A cylinder 17 is connected by a rod 16 to plate 15 to axially position the measuring device. After the race is clamped to the table 2, the cylinder 17 moves the plate to align the member 3 with the raceway, a limit switch then actuating cylinder 29 so that the member is urged by spring 28 into engagement with the raceway, the spring 8 permitting accurate alignment and positioning the member 10 according to the position of the raceway. The probe 6 engages the end face 5 to be ground and grinding is monitored by the tracer to have different feeds until the final distance a is sensed by the probe 10. The end face is thus ground parallel to the centre of the raceway, any offset being eliminated.

Abstract: 1,215,178. Dehydrating foods. SINTEF. 13 Dec., 1968 [18 Dec., 1967], No. 59435/68. Heading F4G. A process of dehydrating food (e.g. meat, fish, shrimps) comprises freezing the food, subdividing the frozen food into particles, distributing the frozen food particles on a movable or fixed carrier (e.g. porous belt or wire cloth) and drying the food by contacting it at atmospheric pressure with a gas (e.g. air, N 2  or CO 2 ) passing through the carrier and having a temperature above the thawing point of the food. Initially the velocity of the gas is such to fluidize the particles whereby thawing occurs so that the particles bind to form a porous mat and then the velocity and optionally the temperature of the gas is gradually increased to the desired values as the firmness of the mat increases. The dried food may be subjected to further drying by a different method.
